For those of you running a straight blog, with no fancy technical additions, there will actually be no problem visible, for the simple reason that you don’t have one.
If, however, you have had the temerity to aspire to the next Geek level, and have added your Twitter feed to your WordPress blog, you will be seeing the same problem as I do:-
The Follower count is never updated!
What happens when the two systems are merged is that the Follower count for the blog is added to the Follower count for Twitter, and the combined count is displayed.
For Twitter users, the Follower count is quite dynamic. I am seeing increases of up to 10 per day, only to be followed by a decrease of 5 the next day, for example. You would expect the combined account to follow the same pattern, but it doesn’t:- it remains completely static as the count calculated when the two systems were merged.
The problem has been reported, and I am awaiting developments.
In the meantime, if you are absolutely desperate to display the burgeoning number of your followers, you can always disconnect Twitter, and then reconnect it – at which time your follower count will be updated to the latest status.
